2 C02 HFC Mags. Brought them with me from Europe. It is WE/TM spec but my hammer spring was not strong enough to get it to work. Selling them as boneyard as I haven’t used them in several years and I’m not sure if they leak or not. They have new Gunsmodfy feedlips. So you can always scrap it for parts. $20 for both of them. Pickup in Vaughan.
